The adsorption of acetone on thin films of amorphous and crystalline ice

摘要: The adsorption of acetone on ice under ultrahigh vacuum (UHV) was investigated with temperature-programmed desorption (TPD) mass spectrometry and Fourier transform infrared reflection absorption spectroscopy (FTIRAS). Two types film, amorphous crystalline, were investigated. On the films, two states observed; one derived from a hydrogen-bonded state second that attributed to physisorbed acetone. Only observed during crystalline films. Infrared confirmed these assignments. This work provides additional evidence surface properties are different those ice.
